如何将元素添加到Mongo DB

Question

我是mongoDB的新手，这是尝试使用push向数组添加一个元素，当我尝试数组progreso或data_pjs没有问题当我尝试将其插入数组datos_progreso时我有问题

/* 1 */ {
    "_id" : ObjectId("5a2a99935887b3f20e1294c6"),
    "__v" : 0,
    "player" : “Player1”,
    "gremio" : "27866",
    "progreso" : [ 
        {
            "gPowerC" : "2,592,335",
            "gPowerS" : "1,594,634",
            "fecha" : ISODate("2017-12-07T17:00:21.000Z"),
            "_id" : ObjectId("5a2a99935887b3f20e1294c7")
        }, 
        {
            "gPowerC" : "5,592,335",
            "gPowerS" : "5,594,634",
            "fecha" : ISODate("2017-12-10T17:00:21.000Z"),
            "_id" : ObjectId("5a2aa12cc24daa1417b35107")
        }
    ],
    "datos_pjs" : [ 
        {
            "name" : "R2-D2",
            "_id" : ObjectId("5a2a99935887b3f20e1295cc"),
            "datos_progreso" : [ 
                {
                    "level" : "85",
                    "gear" : "XII",
                    "power" : "19,873",
                    "star" : "7",
                    "fecha" : ISODate("2017-12-07T17:00:21.000Z"),
                    "_id" : ObjectId("5a2a99935887b3f20e1295cd")
                },
                {
                  /******   HERE ******/
                }
            ]
        }, 
        {
            "name" : "Jyn Erso",
            "_id" : ObjectId("5a2a99935887b3f20e1295ca"),
            "datos_progreso" : [ 
                {
                    "level" : "85",
                    "gear" : "XII",
                    "power" : "19,873",
                    "star" : "7",
                    "fecha" : ISODate("2017-12-07T17:00:21.000Z"),
                    "_id" : ObjectId("5a2a99935887b3f20e1295cb")
                }
            ]
        } 
    ] }

我尝试使用此命令添加元素，但它不起作用，我将推送R2-D2字符中的data_progress矩阵中的元素，同时将REY元素推送到data_pjs，REY push如果适用于我。这两个操作可以同时执行吗？

db.getCollection('pruebas').update ( 
    { "_id" : ObjectId("5a2a99935887b3f20e1294c6") },
    {     
        $push: {    
            "datos_pjs" :  {
                "name" : "R2-D2",
                "_id" : ObjectId("5a2a99935887b3f20e1295cc"),
                "datos_progreso" : {
                    "level" : "87",
                    "gear" : "XII",
                    "power" : "9,873",
                    "star" : "5",
                    "fecha" : ISODate("2017-12-07T17:00:21.000Z"),
                    "_id" : ObjectId()
                }  
            },
            "datos_pjs" :  {
                "name" : "Rey",
                "_id" : ObjectId(),
                "datos_progreso" : {
                    "level" : "85",
                    "gear" : "XII",
                    "power" : "9,873",
                    "star" : "5",
                    "fecha" : ISODate("2017-12-07T17:00:21.000Z"),
                    "_id" : ObjectId()
                }  
            }
        }
    }  
)

任何人都可以帮助我吗？
